Just one final question, over the 6m run, will 15mm piping be sufficient for the fire. I don't want the new fitter to do a botch job. Should I ask him to fit a bigger pipe. I've already trusted one fitter and he's fitted the wrong pipe. I don't want to be in the position again. I've provided the details of the fire below.
pressure 20mb
aeration 8mm x 15mm
injector 390
gas rate m3/h 0.648
input kw (high) 6.8 gross (low) 3.0 gross
Thanks in advance.

15mm will be fine.
You can actually buy a 6m length of plastic coated copper, but I cant think the guy would have a bender for it.
Just tell them on the phone what you want before they waste your time, if that don't know on the phone try another.
PTS do it in 20m coils

Once again mate, many thanks. At least I now know what the fitter needs to be doing.

Beggin your puddin mate, I didin't read it properly!Fireman said:
Confused73 - look at that table I referred you to.
On the 15mm line your "load" is off to the right of 30 metres, for the 1mbar drop, for you cuft/hour figure.
That means a drop of 0.2mbar for your 6 metres, so that's fine.
You might wonder about the 12mm on the chart - it something that's almost never used though.
I'd still urge you to call GSR, or the original guy back. Why pay again
Hi Mick
I'm in Leeds. Obviously, i'd want a proper invoice for the work and would also want to check that you're gas safe registered.

Hi Chris
If i'm understanding you 15mm will defo cover me. As for getting the original guy back, i don't want another botch job and the hassle.

15mm will be fine.
But REALLY, you don't need to buy expensive rolls of coated pipe. You CAN use joints and wrap the pipe.
Having said that, Denso is horrible to work with, and has to be paid for, so I tend to use rigid coated pipe, and Denso the joint area (wearing thin gloves )

Thanks. I'd rather get the job done using a continuous roll. Call me a numpty but my reasoning is less joints = fewer failure points . Anyway, once again thanks to everyone for their help and advice.
my phone number is in my profile if you want to contact me. mick
